Meguire's ultimate compoung
 

will it work taking out light swirl marks doing it by hand?

Yes but you will be tired:lol:. Great product.

There are probably better options out there than going with MUC for light swirling. In fact, being that it's a non-diminishing compound, you may actually introduce just as many problems as you're removing.

For something like this (and sight unseen), I'd go with a product like M-81 or maybe even something back in to the A/G lines of Meg's -- like Color-X or similar.

Heck, to be perfectly honest with you, if the swirls aren't really bad, good ole' cleaner wax isn't a bad option -- again though, sight unseen, it's a tough call.

Like was mentioned, MUC for light swirl removal by hand may be a *very* long day for the aforementioned 'hand'.

I'd try Scratch-X 2.0 before I used UC. It's less abrasive and better suited for application by hand. Color-X is less abrasive.... you may want to try that first.

Another good alternative for hand work from Meguiars consumer line is the Deep Crystal step 1.

That stuff is amazing along with Clay Bar and wax...

I had swirls and acid etching in my paint from the rain. I did a clay bar first then did the entire truck with Ultimate Compound and used a power buffer, then I waxed it. It took about 5+hours, but it looked like it rolled off the showroom floor.

When teamed with the clay bar, the Deep Crystal Step 1 for me gets most of the swirls out of my Charcoal Grey truck color. It is one of my favorite steps when detailing by hand. Why? I have no idea :ll:, but have always enjoyed the results when I team it up with my finishing aray of products.
